D) inorganic and organic compounds.

Question

Quizplus · Accepted Answer

All living microorganisms contain four major classes of macromolecules: amino acids, carbohydrates, lipids, and nucleic acids. These macromolecules are essential for building and maintaining cellular structures, as well as for carrying out cellular processes such as replication, transcription, and translation. While other classes of compounds, such as vitamins and inorganic compounds, may also be present in microorganisms, they are not considered major macromolecules. Similarly, while cellular structures such as cell walls, cytoplasmic membranes, nucleoids, and ribosomes are important components of microorganisms, they are not themselves macromolecules.
